US bill would stop Big Tech favoring its own products

About a dozen U.S. senators from both parties on Monday formally introduced a bill that would bar Big Tech platforms, like Amazon and Alphabet’s Google, from favoring their products and services.
The bill follows others introduced with the goal of reining in the outsized market power of tech firms, including industry leaders Facebook and Apple. Thus far none became law, although one, which would increase resources for antitrust enforcers, passed the Senate.
Senators Amy Klobuchar and Chuck Grassley’s bill would prohibit platforms from requiring companies operating on their sites to purchase the platform’s goods or services and ban them from biasing search results to favor the platform.
